In “Olfaction and risk of dementia in a biracial cohort of older adults,” the authors found an association between worsened olfaction and dementia. Drs. Fuller-Thomson and Jopling suggest the link is cumulative lifetime lead exposure, associated with both deterioration in olfaction and cognitive decline. Older adults, particularly, were exposed to years of airborne lead pollution through leaded gasoline, which was finally phased out in 1991. Authors Freimer and Yaffe agree that continued research into the role of environmental toxins may lead to insights that could help prevent or delay the onset of dementia.
